From Triangle Modernist Houses:
Charles Franklin Knott was born in Durham. He went to NCSU to study architectural engineering but did not graduate. Instead he earned his license through apprenticeship with George Hackney. Knott started with Hackney in 1932, a team that would last 50 years until Knott's death in 1982. Their commercial projects as Hackney and Knott included much of Campbell College (now Campbell University) and the main Durham County Library.
